The first 'lightened' here:
Skua (P. Sketch)
Small rounded head, no pale noseband, greyish shawl are all good pointers for Long-tailed Skua
Skua (Andy House)
Perhaps the above flight image posted is misleading, and it is very small, but my heart would
be pumping seeing that one as it sure looks like an adult Long-tailed Skua to
me... very slim body, no hint of a dark collar on the sides of its breast,
smoky-brown lower belly, ashy-brown (not blackish) underwings that appear to
lack any hint of a pale crescent formed by the pale bases to the primaries of an
Arctic Skua
